    77luke reacted to Superflash007 in GM Module swapping on late model AA Vehciles   
    GM states that VINs in other modules can be corrupted, when and if this happens, any module with a corrupted VIN will need to be replaced.  I have had transmission shops put used transmissions into GM AA vehicles and the TCM will not program as it is VIN locked. These also did not brick the cars.  GM CAN vehicles will not allow programming a used BCM using SPS but the attempt will hurt nothing but time.
     Basically, if you are swapping the listed modules mentioned in the videos, you chance ruining other modules on the AA network or BUS. I have seen it happen as well as not happen. I for one advise my customers that they must use new parts as per GM.
